1. A device comprising:
- a battery charger;
a processor;
a memory accessible to the processor and bearing instructions executable by the processor to;
access a history of at least one previous battery charge by the battery charger;
access calendar information associated with a user of the device;
based on the history, the calendar information, and a current charge level of a battery to be charged by the battery charger, determine an approximate time available to charge the battery, wherein the battery provides power to the device; and
regulate current from the battery charger to the battery to charge the battery to a predetermined capacity to within at least a threshold time of the approximate time available.

Abstract
In one aspect, a device includes a battery charger, a processor, and a memory accessible to the processor. The memory bears instructions executable by the processor to access a history of at least one previous battery charge by the battery charger of a battery powering the device, access calendar information of a user of the device, determine an approximate time available to charge the battery based on the history, the calendar information, and a current charge level of a battery to be charged by the battery charger, and regulate current from the battery charger to the battery to charge the battery to a predetermined capacity to within at least a threshold time of the approximate time available.

11. A method, comprising:
-
initiating charging of a battery; determining a time available to charge the battery; and based at least partially on the time available, increasing or decreasing current to the battery from an initial current, the initial current being used at the initiating of the charging of the battery. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system, comprising:
-
an information handling system to be powered; and a battery charger for charging at least one battery, wherein the battery powers the information handling system; wherein the information handling system includes; a processor; a memory accessible to the processor and bearing instructions executable by the processor to; access information to determine a current time available for charging the battery from its current charge level to a fully charged level; determine the current time available for charging the battery from its current charge level to the fully charged level at least partially based on the information; modulate current from the battery charger to the battery to charge the battery to a threshold charge amount below the fully charged level prior to a threshold time, the threshold time being a time before the end of the current time available for charging the battery; and modulate current from the battery charger to the battery to charge the battery to the fully charged level after the threshold time. - View Dependent Claims (18, 19, 20)
